- Dichromatism (or polychromatism) is a phenomenon where the hue of the colour in materials or solutions are dependent on both the concentration of the absorbing substance and the depth or thickness of the medium traversed. ...
- Color differences between individuals of the same species.
- Color vision involving only two pigments.
- Two different color receptors which describes the three different types of color blindness protanopia, deuteranopia and tritanopia.
- Sensitivity to two colors rather than the three needed to perceive all the colors in the spectrum by combining primary colors.
- A form of defective color vision in which a mixture of only two can match all colors. In dichromatic vision, the spectrum is seen as comprising only two regions of different hue separated by an achromatic band. ...
